To all whom it may concern: 7

. v Be it known that I, J OHN-C. Fmnn'cun'r, a citizen of the UnitedStates, residing at Akron; in the count of Summit and State of Ohio,have invent certain new Improvements in Fluid-Extracting Presses, ofwhich the following is a specification. V

This invention relates to animprovement in a fluid extracting press, allsubstantially as herein set forth and more particularly pointed out inthe claims.

- In'the various forms of presses patented by me heretofore, I haveexperienced diflicult in effecting a proper escape of the flui and inholding back the solids. Thus,

one diiliculty consisted in preventing buckling or displacement ofcertainpartsandin maintaining uniform spaces forthe esca of the oil. Thesolids would alsopack 1n places. The object of the presentimprovement isto provide an effective arrangement of parts to overcome suchdifficulties, and to provide a movement which will facilitate the escapeof the fluid and prevent the escape openings-from clogging, and afurther ob ect is to simplify the structure and re duce its costandupkeep to a minimum. I

In the accompanying drawin Figure 1v is a sectional view longitudina ythrough the shell of the press. Fig. 2 is a cross section of the presson line 22, Fig. 1. V Fig. 3

I is an enlarged view and sectional detail of one of the fluiddistributing ducts or channels in the spiral wall of the rotating body.

4 is a perspective view of oneof the divislon walls used between thebaflle members.

. In one form of the invention the prem comprises a casing or shell--'2.cast in-one pieceor otherwise formed to provide an in-- tegralcylindrical inclosure for one or more -.rotary pressing members. Thus, Imay use a two rotor members 3 and 4 geared to rotate in oppositedirections at the same speed,-o1, I may omit the gearing andmodifytheconstruction in other ways W1i3h011t1 affecting ,thefpresentimprovement.- As shown, however, a main feed and presser member 3 isprovided with a hollow shaft or integral. "shaft extensions 5 which areadapted to rotate in hearings in suitable standards 6 and 7, and asecond baflle member 4 is mounted on a shaft 8 having bearing instandard 6 and-in the wall 9 of shell'---2-i The body of rotor member 3is round and tapered, and

the bore or chamber 1 in shell 2 for rotor member 3' has a slight taperwith a flarir1ttg= exit'll at one end. This exit may be open or arrangedto'be opened or closed, more or less, by a flanged cone-shaped rin 12secured to the end of shell 2 by. bolts an notched baflle portion 4oppositethe division wall 15 of member 3.

Therotor member 3 is in effect a screw length witha spiral thread orflight and a spiral circumferential channel 14 for the material, and thebaflles 4 are mounted to rotate inthe annular circumferential channelbetween the annular division walls 15 at the feed end of the press andare slotted to re-' ceive the cross connecting portions of the divisionwalls so asgto press thematerial and extract the fluid therefromduring-its forced travel forward in the channel. table divisionplates-4f are also placed between the notched baflle walls 4 directlyop--. posite each annular wall 15' to prevent the drainage openings insuch divlsion walls from being uncovered and the solids from passinginto said openings.

The present Inventiomis distinguished, more particularly, in the meansprovided for permitt the fluid to escape from the spiral channe 14,"regardless of whether one pressing member or two or more are emloyedThus, the annular and spiral di- Non-rotanuts. The material is fed intothe shell I through a hopper 13 or in any suitable way,

and division plates 4 are placed between the member in that it isprovided overits main vision wall or flight- 15 forming the channel 14is made relatively wide and of a. diameter to bring its peripheralsurface in close pi'ox imity to the curved surfaceof bore 10, and

the-space allowed may be varied slightly by v adjustment of the rotormember longtudinally in the tapered bore 10 so that o the fluid and notthe materialmay escape. The circumferential edge or periphery ofdivision wall 15 is also preferably provided with a peripheral gmo've 16to receive the fluid which escapes from channel 14, and the fluid thusgathered up is discharged through a series of tubes 17 extending fromsaid ve and radially in rotor member 3 to a central -,longitudinal opeThis opening 18 has outlet t ugh one or both of the hollow shafts orshaft extensions 5, and the tubes 17 are preferably-of tapering orflaring form internally with the 18 therein.

larger. inner ends open to the main discharge opening 18, therebyproviding for av 5 we into them.

he construction of the press is greatly simplified by using a solidshell and forming fluid outlets in the circumferential helical divisionwall or flights 15 of the rotor member as described, and the escape ofthe fluid is materially improved and proceeds continuously with aneflectiveexclusion of the materialfrom the fluid passages. The solid orintegral shell can be constructed at less expensethan a slotted orperforated or sectional shell made of special rings, and 1t may consistof a cast body with a hardened and relatively thin metal bushing adaptedto be replaced when worn out. The size of the escape openings, whenaccurately determined, are not altered or changed by wear or use of themachine, and the escape of the oil is uniform and constant at all pointsthe full length of the shell. With the present a construction it isaneasy matter to determine the proper size of opening and maintain theopening to size without any trouble or great expense. r v

The movement of the material is longitudinally of the shell, and in therotation of the pressing member 3 the oil follows the roove or channelin the periphery of the ight and each radial opening Wlll carry the oilaway while coming constantly opposite all parts ofthe cake, that is, thematerial compressed in the channeL, The holes or openings through theflights are also made large enough so that all particles escaping fromthe channels can not clog such openings, and the taper also preventssuch clogging. J

The machine shown is supported on a base with the rotor member 3operating in a horizontal plane, that is, on a horizontal axis. However,I wish it to be understood that I may support the shell and screw memberin a vertical position and any suitable means may be used to adjust theshell or screw member relatively to each other so that the space betweenthe shell and the flights of the screw may be of uniform size and nounequal wear produced.

In one form of press patented byme I use a conical worm or screw withina divided casing of conical form, and emplo a different form' of bafilemember at the fee end ofthe press, and in a press of that or kindredtype it is not desirable to continue the perip eral channel and makedrainage openings in the flights at the'feed end of the press.Therefore, I do not limit myself to the use of the drainage openingsthroughout the full length of the flights vas they may be used in only aportion of their a length and where most effective.
